Fluidall's 25 Gallon Capacity DEF Storage Cart is mobile built on a steel frame with large casters for ease of dispensing DEF around the shop. The cylindrical tank is transparent so that a visual DEF fluid inventory can be checked. In addition the DEF cart is refillable from bulk storage. Our standard DEF dispense package includes a DEF manual hand pump, 6² hose and a manual nozzel. However, the DEF cart can be upgraded with other metered and non-metered dispense packages.
